Larva, when full grown, about an inch and a quarter long. Head 

 dull red with a V-shaped mark on the front, yellow above and 

 marked with many longitudinal black lines ; the under side paler. 

 Like the larva of the Canker-worm it is a span or inch worm but 

 larger than the caterpillar of that species. The accompanying cut 

 (Fig. 7) shows the larvae feeding and at rest.

Male, wingless 



Female Moth, wingless, spider-like, yellowish white, sides marked 

 with black dots, each ring of the body, excepting the last, bears- 

 two black dots, which has only one. Head black in front and the 

 legs ringed with black. Antennae thread like. Ovipositor jointed 

 and retractile. The larger size, the spotted back and black rings 

 on the legs readily distinguish this from the wingless females of 

 the fall and spring Canker-worms. Fig. 7 shows the wingless 

 female about natural size.
